Questions
Is there a KiCad symbol and footprint for the CMS4946A?
Yes. the footprint Package_SO:SOP-8_3.76x4.96mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the CMS4946A?
SOP-8, with 8 pins. Its footprint is drawn on this page.
Where is the CMS4946A datasheet?
Cmos publishes it: the Datasheet link on this page opens it.
Where can I order the CMS4946A?
JLCPCB lists it as part C20625159, with 3,773 in stock; the sellers' links on this page open their listings.
What can replace the CMS4946A?
Parts like it in the library: the 9958 by HL, the FDS86140-TP by TECH PUBLIC, the TPSI4090DY-T1-GE3 by TECH PUBLIC and the WSP6949 by Winsok Semicon. Check their datasheets: a part that fits the footprint may still differ in its ratings.
